There are inventions out there for cats that seem really outlandish to me, but maybe it’s because I don’t have a cat. The are false teeth for cats, kitty litter contraptions hidden inside furniture, ottomans for cats that are made out of sandpaper so cats can keep their nails (paws?) well-manicured, and now we can add RFID cat flaps to the list."
